Hey guys, I posted this under the Fuller's ESB/London Pride thread that hasn't been active for a few months, as well. I figured I could start a new thread since my question is related more the parti gyle in general. Could kill two bird with one stone:
I'm still a little confused after listening to the show. They say, for parti gyle, that they blend the runnings in different parts for the two different beers. How is this any different from sparging and running off into the kettle that already has an "x" amount of your first runnings? Doesn't the gravity just change at this point since you're diluting the first runnings with second runnings until you hit the gravity you want?
Do you blend ever after the boil?
The reason I ask is because in the show, he said that he takes the first runnings and then boils them for the ESB. He then takes the second runnings and uses them for the London Pride. I thought the runnings were supposed to be blended?
I'm really trying to figure out why exactly the parti gyle is necessary, when they say it is necessary...along with how the blending process works. I get that parti gyle was originally used to create different beers and different gravities.
